Signals2: Managed signals
& slots callback implementation (thread-safe version 2), from Frank Mori
Hess.
Updated Libraries
Asio:
... [More]
Implement automatic resizing of the bucket array in the internal hash
maps. This is to improve performance for very large numbers of asynchronous
operations and also to reduce memory usage for very small numbers. A
new macro BOOST_ASIO_HASH_MAP_BUCKETS
may be used to tweak the sizes used for the bucket arrays.
Add performance optimisation for the Windows IOCP backend for when no
timers are used.
Prevent locale settings from affecting formatting of TCP and UDP endpoints
(#2682).
Fix a memory leak that occurred when an asynchronous SSL operation's
completion handler threw an exception (#2910).
Fix the implementation of io_control() so that it adheres to the documented
type requirements for IoControlCommand (#2820).
Fix incompatibility between Asio and ncurses.h (#2156).
On Windows, specifically handle the case when an overlapped ReadFile call fails with ERROR_MORE_DATA. This enables a hack
where a windows::stream_handle can be used with a message-oriented
named pipe (#2936).
Fix system call wrappers to always clear the error on success, as POSIX
allows successful system calls to modify errno (#2953).
Don't include termios.h if BOOST_ASIO_DISABLE_SERIAL_PORT
is defined (#2917).
Cleaned up some more MSVC level 4 warnings (#2828).
Various documentation fixes (#2871).
Flyweight:
The refcounted
component was not thread-safe due to an incorrect implementation and
could deadlock under heavy usage conditions. This problem has been corrected.
Foreach:
Eliminate shadow warnings on gcc for nested FOREACH
loops
Portability fix for Intel-Win toolset
Hash:
Remove deprecated headers for hashing containers. Everything that was
in them is included in <functional/hash.hpp>
(#2412).
Other minor changes, full details in the library change
log.
Interprocess:
Increased portability and bug fixes. Full details in the library change
log.
Intrusive:
Optimizations and bug fixes. Full details in the library change
log.
Program.Options:
Multitoken options fixed (#469).
Proto:
Work around incompatibility with standard Linux header.
Add proto::noinvoke<>
to block metafunction invocation in object transforms.
PtrContainer:
Bug fixes from Trac applied.
Range:
Bug fixes from Trac applied.
Unordered:
Fixed regression in 1.38 that prevented unordered from using more than
about 1.5 million buckets (#2975).
Minor implementation changes, including #2756.
Full details in the library change
log.
Xpressive:
Work around for gcc optimization problem resulting in pure virtual function
call runtime error (#2655).
Updated Tools
Boostbook:
Improved PDF generation.
Preliminary HTMLHelp support.
Add default path for callout images.
Include data members' <purpose>
in the class synopsis.
Fix bug where a function's <purpose>
wasn't displayed if it was just plain text.
Support the alt tag in <headername>
and <macroname>. Use this if the header or macro
name is different to the contents of the tag (#1977).
Support links relative to the boost root in <ulink>
tags, using a custom url, see the linking
documentation for details (#1166).
Avoid generating filenames that only differ in case for function, method
and macro documentation.
Run the docbook chunker quietly, unless boostbook.verbose is set. This
parameter might be used in other places in future releases.
Make the 1.1 DTD available.
Fill in some missing reference documentation (partially fixes #2153).
Changes to doxygen integration:
Support \throw.
Support global variables and enums.
Better support for documentation written in function and method bodies.
Workaround a problem with doxygen 1.5.8's xml output (#2937).
Quickbook:
Return an error code and error count if there are any errors (#1399).
Support both windows and cygwin paths at the compile line when compiled
with cygwin.
Fix some issues with C++ and Python code:
Fail gracefully for a mismatched ''.
Warn if any unexpected character are encountered and write them out
properly (#1170).
Fix a bug for hex encoded characters in strings (#2860).
Improved testing, including tests for expected failures.
Generate valid document info for document types other than library (#2711):
Remove library specific attributes.
Put title before info block.
Fix a bug when calling templates.
Less warnings when built using gcc.
Small documentation improvements (#1213,
#2701).

history
Exception:
Improved and more customizable diagnostic_information
output.
Filesystem:
Fix native(name) test failures on POSIX-like systems.
Several bugfixes (#2543,
#2224,
#2531,
#1840,

Graph:
Added a new algorithms for Travelling Salesman Problem approximation
(metric_tsp_approx) and
resource-constrained Shortest Paths (r_c_shortest_paths).
Support for named vertices in adjacency_list.
A number of bugfixes ( #416,
#1622,
#1700,
#2209,
#2392,
#2460,
and #2550)
Hash:
boost/functional/detail/container_fwd.hpp has been moved to boost/detail/container_fwd.hpp. The current location is deprecated.
For more detail, see the library
changelog.
Interprocess:
Updated documentation to show rvalue-references functions instead of
emulation functions.
More non-copyable classes are now movable.
Move-constructor and assignments now leave moved object in default-constructed
state instead of just swapping contents.
Several bugfixes (#2391,
#2431,
#1390,
#2570,
#2528).
Intrusive:
New treap-based containers: treap, treap_set, treap_multiset.
Corrected compilation bug for Windows-based 64 bit compilers.
Corrected exception-safety bugs in container constructors.
Updated documentation to show rvalue-references functions instead of

Added Johan Råde's optimised floating point classification routines.
Fixed code so that it compiles in GCC's -pedantic mode (bug report #1451).
Multi-index Containers:
Some
redundant type definitions have been deprecated. Consult the library release notes
for further information.
Proto:
Fix problem with SFINAE of binary operators (Bug 2407).
Fix proto::call transform for callable transforms

Support for nullary expressions with tag types other than proto::tag::terminal
Allow 0- and 1-argument variants of proto::or_
and proto::and_
Regex:
Breaking change: empty expressions,
and empty alternatives are now allowed when using the Perl regular expression
syntax. This change has been added for Perl compatibility, when the new
syntax_option_type no_empty_expressions
is set then the old behaviour is preserved and empty expressions are
prohibited. This is issue #1081.
Added support for Perl style ${n} expressions in format strings (issue
#2556).
Added support for accessing the location of sub-expressions within the
regular expression string (issue #2269).
Fixed compiler compatibility issues #2244,
#2514,
and #2458.
Thread:
No longer catches unhandled exceptions in threads as this debuggers couldn't
identify the cause of unhandled exceptions in threads. An unhandled exception
will still cause the application to terminate.
TR1:
Added support for the TR1 math functions and the unordered containers.
Type Traits:
Added support for Codegear intrinsics.
Minor tweaks to warning suppression and alignment_of code.
Unordered:
Use boost::swap.
Use a larger prime number list for selecting the number of buckets.
Use aligned
storage to store the types.
Add support for C 0x initializer lists where they're available.
For more detail, see the library
changelog.
Xpressive:
basic_regex gets nested
syntax_option_flags and
value_type typedef, for
compatibility with std::basic_regex
Ported to Proto v4; Proto v2 at boost/xpressive/proto
has been removed.
regex_error inherits
from boost::exception
Other Changes
Experimental support for building Boost with CMake
has been introduced in this version. For more details see the wiki,
Discussion is taking place on the Boost-cmake
mailing list.
Fixed subversion properties for several files. Most notably, unix shell scripts
should always have unix line endings, even in the windows packages.

New Libraries
Flyweight:
Design pattern to manage large quantities of highly redundant objects,
from Joaquín M López Muñoz.
ScopeExit:
Execute
... [More]
arbitrary code at scope exit, from Alexander Nasonov.
Swap:
Enhanced generic swap function, from Joseph Gauterin.
Updated Libraries
Accumulators:
Add rolling_sum, rolling_count and rolling_mean
accumulators.
Any:
Use a by-value argument for operator= (#2311).
Asio:
Improved compatibility with some Windows firewall software.
Ensured arguments to windows::overlapped_ptr::complete() are correctly passed to the completion
handler (#2614).
Fixed a link problem and multicast failure on QNX (#2504,
#2530).
Fixed a compile error in SSL support on MinGW / g++ 3.4.5.
Drop back to using a pipe for notification if eventfd is not available
at runtime on Linux (#2683).
Various minor bug and documentation fixes (#2534,
#2541,
#2607,
#2617,
#2619)
Config:
Add new macros BOOST_NO_STD_UNORDERED and BOOST_NO_INITIALIZER_LISTS.
Added Codegear compiler support.
Added Dragonfly to the BSD family of configs.
Updated MSVC's binary ABI settings to match compiler default when doing
64-bit builds.
Recognise latest compilers from MS and Intel.
Date_Time:
Added support for formatting and reading time durations longer than 24
hours with new formatter: %0.
Removed the testfrmwk.hpp
file from the public include directory.
Fixed several bugs and compile errors.
For full details see the change
history
Exception:
Improved and more customizable diagnostic_information
output.
Filesystem:
Fix native(name) test failures on POSIX-like systems.
Several bugfixes (#2543,
#2224,
#2531,
#1840,
#2542).
Graph:
Added a new algorithms for Travelling Salesman Problem approximation
(metric_tsp_approx) and
resource-constrained Shortest Paths (r_c_shortest_paths).
Support for named vertices in adjacency_list.
A number of bugfixes ( #416,
#1622,
#1700,
#2209,
#2392,
#2460,
and #2550)
Hash:
boost/functional/detail/container_fwd.hpp has been moved to boost/detail/container_fwd.hpp. The current location is deprecated.
For more detail, see the library
changelog.
Interprocess:
Updated documentation to show rvalue-references functions instead of
emulation functions.
More non-copyable classes are now movable.
Move-constructor and assignments now leave moved object in default-constructed
state instead of just swapping contents.
Several bugfixes (#2391,
#2431,
#1390,
#2570,
#2528).
Intrusive:
New treap-based containers: treap, treap_set, treap_multiset.
Corrected compilation bug for Windows-based 64 bit compilers.
Corrected exception-safety bugs in container constructors.
Updated documentation to show rvalue-references functions instead of
emulation functions.
Lexical Cast:
Changed to work without RTTI when BOOST_NO_TYPEID
is defined (#1220).
Math:
Added Johan Råde's optimised floating point classification routines.
Fixed code so that it compiles in GCC's -pedantic mode (bug report #1451).
Multi-index Containers:
Some
redundant type definitions have been deprecated. Consult the library release notes
for further information.
Proto:
Fix problem with SFINAE of binary operators (Bug 2407).
Fix proto::call transform for callable transforms
with >3 arguments.
result_of::value changed behavior for array-by-value
terminals.
unpack_expr requires
only Forward Sequences rather than Random Access Sequences.
Deprecate legacy undocumented BOOST_PROTO_DEFINE_(VARARG_)FUNCTION_TEMPLATE
macros.
Add BOOST_PROTO_REPEAT
and BOOST_PROTO_LOCAL_ITERATE
macros to help with repetitive code generation
Support for nullary expressions with tag types other than proto::tag::terminal
Allow 0- and 1-argument variants of proto::or_
and proto::and_
Regex:
Breaking change: empty expressions,
and empty alternatives are now allowed when using the Perl regular expression
syntax. This change has been added for Perl compatibility, when the new
syntax_option_type no_empty_expressions
is set then the old behaviour is preserved and empty expressions are
prohibited. This is issue #1081.
Added support for Perl style ${n} expressions in format strings (issue
#2556).
Added support for accessing the location of sub-expressions within the
regular expression string (issue #2269).
Fixed compiler compatibility issues #2244,
#2514,
and #2458.
Thread:
No longer catches unhandled exceptions in threads as this debuggers couldn't
identify the cause of unhandled exceptions in threads. An unhandled exception
will still cause the application to terminate.
TR1:
Added support for the TR1 math functions and the unordered containers.
Type Traits:
Added support for Codegear intrinsics.
Minor tweaks to warning suppression and alignment_of code.
Unordered:
Use boost::swap.
Use a larger prime number list for selecting the number of buckets.
Use aligned
storage to store the types.
Add support for C++0x initializer lists where they're available.
For more detail, see the library
changelog.
Xpressive:
basic_regex gets nested
syntax_option_flags and
value_type typedef, for
compatibility with std::basic_regex
Ported to Proto v4; Proto v2 at boost/xpressive/proto
has been removed.
regex_error inherits
from boost::exception
Other Changes
Experimental support for building Boost with CMake
has been introduced in this version. For more details see the wiki,
Discussion is taking place on the Boost-cmake
mailing list.
Fixed subversion properties for several files. Most notably, unix shell scripts
should always have unix line endings, even in the windows packages.
